NAME
pthread_attr_init,
pthread_attr_destroy —
initialise and destroy threads
attribute object
SYNOPSIS
#include
<pthread.h>
int
pthread_attr_init(pthread_attr_t
*attr);
int
pthread_attr_destroy(pthread_attr_t
*attr);
DESCRIPTION
The functionpthread_attr_init()
initialises a thread attributes object attr with the
default value for all of the individual attributes used by a given
implementation.
The resulting attribute object (possibly modified by setting individual attribute values), when used by pthread_create(3), defines the attributes of the thread created. A single attributes object can be used in multiple simultaneous calls to pthread_create(3).
The
pthread_attr_destroy()
function is used to destroy a thread attributes object. An implementation
may cause pthread_attr_destroy() to set
attr to an implementation-dependent invalid value. The
behaviour of using the attribute after it has been destroyed is
undefined.
RETURN VALUES
Upon successful completion,
pthread_attr_init() and
pthread_attr_destroy() return a value of 0.
Otherwise, an error number is returned to indicate the error.
ERRORS
The pthread_attr_init() function will fail
if:
- [
ENOMEM] - Insufficient memory exists to initialise the thread attributes object.
These functions will not return an error code of
[EINTR].
